get one's end away

British slang meaning to have sex, especially framed from a male perspective as successfully achieving one's goal of getting laid. The phrase has a jaunty, somewhat dated quality — more pub banter circa 1970s than modern social media — but it remains widely understood across the UK. The 'end' is a euphemism rooted in innuendo, and 'away' implies a triumphant departure or completion. Occasionally still deployed for comedic effect or nostalgic irony.
